This cartridge last forever. In fact this time we put a date on it as we dropped it in as to remember how long it will last. It seems it is like the commercial you see that says it keeps going and going and going. Since the cartridge is expensive at over one hundred and fifty dollars, we are glad to see it keep going and not have to replace it very soon. It gives a great quality print and it easy to drop in the printer. The recycling feature with the label enclosed is also great as you just pack up the old and on with the new
